Abstract

SEGMENTO DE LÂMINA PARA UM REFINADOR, E, REFINADOR PARA REFINAR MATERIAL FIBROSO. Um segmento de lâmina (4, 8) para um refinador (1) para refinar material fibroso. O segmento de lâmina compreende uma primeira (20) e uma segunda (21) arestas de extremidade e uma primeira (22) e uma segunda (23) arestas laterais opostas à primeira aresta lateral (22) e uma superfície de refino (5, 9) compreendendo barras de lâminas (27, 27a, 27b) e sulcos de lâminas (28, 28a, 28b) entre as mesmas em uma superfície frontal (25) do segmento de lâmina. O segmento de lâmina compreende adicionalmente pelo menos uma abertura (14, 15) pelo menos em uma aresta lateral (22, 23), a abertura se estendendo através de toda a espessura de um corpo do segmento de lâmina (24), bem como pelo menos um sulco de alimentação (29) na superfície de refino, o sulco de alimentação (29) se estendendo a partir da abertura e cruzando as barras de lâminas e os sulcos de lâminas para alimentar o material a ser refinado através da superfície de refino. As barras de lâminas (27, 27a, 27b) do segmento de lâmina são entrelaçadas no sulco de alimentação.BLADE SEGMENT FOR A REFINER, AND, REFINER FOR REFINING FIBROUS MATERIAL. A blade segment (4, 8) for a refiner (1) for refining fibrous material. The blade segment comprises a first (20) and a second (21) end edge and a first (22) and a second (23) side edge opposite the first side edge (22) and a refining surface (5, 9 ) comprising blade bars (27, 27a, 27b) and blade grooves (28, 28a, 28b) therebetween in a front surface (25) of the blade segment. The blade segment further comprises at least one aperture (14, 15) at at least one side edge (22, 23), the aperture extending through the entire thickness of a body of the blade segment (24) as well as at least at least one feed groove (29) in the refining surface, the feed groove (29) extending from the aperture and crossing the blade bars and blade grooves to feed the material to be refined through the refining surface. The blade bars (27, 27a, 27b) of the blade segment are interlaced in the feed groove.
